Senior 3D Unreal Engine Engineer

Company Overview

Sigmawave AI is a visual synthetic data company helping organisations build better computer vision and AI systems. We provide configurable, high-quality synthetic datasets that support model training, testing, and validation—delivered safely, efficiently, and at scale.

Job Description

We are seeking a Senior 3D Unreal Engine Engineer to join our 3D & Simulation team. You will be responsible for designing, developing, and maintaining high-performance plugins and tools within Unreal Engine that power our synthetic data generation pipeline. Your work will enable scalable, artist-friendly workflows for creating high-fidelity 3D environments and assets used to train next-generation Vision AI models.

Key Responsibilities

Design, build, and maintain robust Unreal Engine plugins in C++ to extend engine functionality, automate content production, and integrate with our proprietary synthetic data platform. Develop and optimize Blueprint systems that empower technical artists and content creators to assemble complex scenes, configure sensors, and define scenarios without deep programming. Collaborate closely with 3D artists, ML engineers, and platform teams to understand pipeline bottlenecks and implement tooling that improves throughput, quality, and iteration speed. Architect and implement core systems for asset management, procedural placement, lighting, camera simulation, and batch rendering within Unreal. Write performant, well-documented, and scalable code following Unreal best practices and modern software engineering standards. Profile and optimize rendering and simulation performance for both real-time editor workflows and high-throughput offline rendering farms.

Required Qualifications

5+ years of professional experience with Unreal Engine in a production environment. Expert-level C++ proficiency with deep experience in Unreal's codebase, module system, and plugin architecture. Proven experience developing and releasing Unreal Engine plugins or tools (in-house or commercial). Strong fluency in Blueprints for creating user-facing tools, gameplay systems, or workflow automation. Solid understanding of 3D mathematics, real-time rendering, and game engine architecture. Experience with source control (Git, Perforce) and collaborative development workflows. Ability to translate artistic and technical requirements into robust engineered solutions.

Nice to Have

Experience releasing or maintaining a commercial plugin on the Unreal Marketplace (Fab). Familiarity with Python for tooling or automation outside Unreal. Knowledge of rendering optimization, GPU profiling, or Vulkan/DirectX12. Background in computer vision, synthetic data, or simulation for ML. Experience with 3D asset pipelines (USD, FBX, GLTF) and DCC tools (Blender, Maya, Houdini).

What We Offer

High-impact role building core 3D technology for a production synthetic data platform. Opportunity to work on cutting-edge problems at the intersection of real-time 3D, simulation, and AI. Collaborative, cross-functional environment with teams in AI, 3D art, and platform engineering. Competitive compensation and equity package. Flexible hybrid/remote work arrangements.
